Impulsivity and BOLD fMRI activation in MDMA users and healthy control subjects
Psychiatry Research-neuroimaging, 2006Co-Authors: Ignacio Valdes, Ernest S Barratt, Donald M. Dougherty, Joel L. Steinberg, Ponnada A. Narayana, Larry A. Kramer, Alan C. Swann, F.g. MoellerAbstract:The correlation between scores on the Barratt Impulsiveness Scale (BIS) and activation measured by functional magnetic resonance imaging in a dorsolateral prefrontal cortical (DLPFC) activating task was examined in 15 MDMA-using subjects and 19 controls. A significant correlation between BIS scores and DLPFC activation was found, supporting a role for the DLPFC in BIS-measured impulsivity.

psychometric properties of an italian version of the Barratt Impulsiveness Scale 11 bis 11 in nonclinical subjects
Journal of Clinical Psychology, 2001Co-Authors: Andrea Fossati, Elena Acquarini, Antonella Di Ceglie, Ernest S BarrattAbstract:To assess the psychometric properties of the Italian translation of the Barratt Impulsiveness Scale-11 (BIS-11), the Scale was administered to 763 college undergraduates. Based on analyses using item-total correlations and t-tests for differences between the top and the bottom total score quartiles, all items from the English version of the BIS-11 were retained in the Italian version. Cronbach's α for internal consistency was .79 and two-month test–retest reliability was .89. An exploratory principal-components analysis replicated the six first-order factors and three oblique second-order factors, consistent with the number identified in the English version. However, subfactor item loadings differed between the English and Italian versions. The overall item pool was consistent in being a homogeneous measure of Impulsiveness. The BIS-11 total score was correlated significantly with aggression and ADHD measures. The BIS-11 also significantly differentiated between high and low levels of binge eating, alcohol consumption, and cigarette smoking. © 2001 John Wiley & Sons, Inc. J Clin Psychol 57: 815–828, 2001.

Factor structure of the Barratt Impulsiveness Scale
Journal of Clinical Psychology, 1995Co-Authors: Jim H. Patton, Matthew S Stanford, Ernest S BarrattAbstract:The purpose of the present study was to revise the Barratt Impulsiveness Scale Version 10 (BIS-10), identify the factor structure of the items among normals, and compare their scores on the revised form (BIS-11) with psychiatric inpatients and prison inmates. The Scale was administered to 412 college undergraduates, 248 psychiatric inpatients, and 73 male prison inmates. Exploratory principal components analysis of the items identified six primary factors and three second-order factors. The three second-order factors were labeled Attentional Impulsiveness, Motor Impulsiveness, and Nonplanning Impulsiveness. Two of the three second-order factors identified in the BIS-11 were consistent with those proposed by Barratt (1985), but no cognitive Impulsiveness component was identified per se. The results of the present study suggest that the total score of the BIS-11 is an internally consistent measure of Impulsiveness and has potential clinical utility for measuring Impulsiveness among selected patient and inmate populations.

Confirmatory factor analysis of the Barratt Impulsiveness Scale-short form (BIS-15) in patients with mental disorders.
Psychiatry research, 2019Co-Authors: Adrian Meule, Silke Michalek, Hans-christoph Friederich, Timo BrockmeyerAbstract:Abstract Impulsivity is a major component of various mental disorders. A short form of the Barratt Impulsiveness Scale—the BIS–15—assesses three facets of impulsivity: non-planning, motor, and attentional. A confirmatory factor analysis tested its factor structure composed of three first-order latent factors and a second-order impulsivity factor in 453 patients with mental disorders (64% female). Model fit was acceptable as were internal reliabilities of the subScales and the total Scale. The BIS–15 has sound psychometric properties in patients with mental disorders and, thus, can be used for assessing impulsivity and its subcomponents in this population.

Adrian Meule, Hospital for Child and Adolescent Psychiatry, LWL University Hospital of the Ruhr University Bochum, Heithofer Allee 64, 59071 Hamm, Germany. Email: adrian.meule{at}rub.de One of the most widely used instruments for the measurement of impulsivity is the Barratt Impulsiveness Scale (BIS-11). The short form of the BIS-11, the BIS-15, consists of 15 items representing the three subScales Attentional, Motor , and Non-Planning Impulsivity . In the current study, retest-reliabilities of BIS-15 scores were examined. Female university students completed the BIS-15 at the beginning of the first ( n = 133) and second ( n = 120) semesters. Half-year retest-reliability was r tt = .79 for the BIS-15 total score and ranged between r tt = .61 and .78 for the subScales. Considering the long time span of almost half a year between measurements, the total score of the BIS-15 has high retest-reliability and, thus, measures impulsivity as a stable personality trait.

psychometrische evaluation der deutschen Barratt Impulsiveness Scale kurzversion bis 15
Diagnostica, 2011Co-Authors: Adrian Meule, Claus Vögele, Andrea KüblerAbstract:Zusammenfassung. Impulsivitat ist ein Personlichkeitsmerkmal, das mit schnellen, unuberlegten Handlungen ohne Beachtung moglicher negativer Konsequenzen einhergeht. Eines der am weitesten verbreiteten Verfahren zur Erfassung von Impulsivitat ist die Barratt Impulsiveness Scale (BIS-11; Patton, Stanford & Barratt, 1995). Es wurde gezeigt, dass die drei Faktoren nicht-planende, motorische und aufmerksamkeitsbasierte Impulsivitat auch ausreichend gut mit einer verkurzten Form der BIS-11 erfasst werden konnen (BIS-15; Spinella, 2007). Die vorliegende Arbeit stellt diese Kurzversion der BIS-11 in einer deutschen Ubersetzung vor. Reliabilitat und Faktorstruktur des Fragebogens wurden in einer Stichprobe (N = 752) von uberwiegend Studierenden getestet. Die dreifaktorielle Struktur von Spinella (2007) konnte bestatigt werden. Die interne Konsistenz war gut (Cronbachs α = .81). In einer zweiten Studie (N = 51) zeigte sich konvergente Validitat durch Zusammenhange mit einem anderen Impulsivitatsmas (UPPS). Die BIS-...

Lack of association between the serotonin transporter promoter gene polymorphism and impulsivity or aggressive behavior among suicide attempters and healthy volunteers
Psychiatry research, 2004Co-Authors: Enrique Baca-garcía, Concepción Vaquero, Carmen Diaz-sastre, Eloy Garcia-resa, Jeronimo Saiz-ruiz, José Fernández-piqueras, Jose De LeonAbstract:The association between a polymorphism in the promoter area of the serotonin transporter (17q11.1-q12) with impulsivity and history of aggressive behavior was studied in a Spanish general hospital. Subjects comprised 216 suicide attempters (152 women and 64 men) and 223 control blood donors (124 women and 99 men). They were classified as S individuals (s/s or s/l) with low expression of the serotonin transporter, and L individuals (l/l) with high expression. The genotype was not associated with high levels of impulsivity (measured with the Barratt Impulsiveness Scale) or history of aggressive behavior (measured with the Brown-Goodwin Scale). This lack of association did not appear to be explained by lack of statistical power. High scores on the Barratt Impulsiveness Scale (BIS) and the Brown-Goodwin Aggressive Behavior Scale were associated with being an attempter, male gender and borderline personality disorder. While our Spanish suicide attempters and published US suicide attempters have similar BIS scores, our Spanish suicide attempters have significantly lower aggressive behavior scores. If cross-cultural differences in aggressive behavior scores are definitively established, country norms for aggressive behavior Scales will need to be developed to compare genetic studies in different countries.

EPA-0537 – Barratt Impulsiveness Scale as a possible marker of seasonality in suicide attempts
European Psychiatry, 2014Co-Authors: A. Lains, E. Baca García, E. Verdura VizcaínoAbstract:In 2011, 3.429 people committed suicide in Spain. It is currently the first cause of unnatural death is this country, ahead of road traffic accidents. Seasonality in consummated suicides has been well established in the literature. Consistently, suicides employing violent methods have been described to have higher seasonal variations than non-violent suicides. Violent suicide methods have been associated with a higher level of lifetime aggression and higher levels of impulsivity. The literature is scarcer regarding seasonality in suicide attempts, although, to a lesser extent, seasonal patterns have also been described. It has been argued that, due to the lower prevalence of violent methods in attempted suicides, it is not surprising to find a weaker seasonal effect. In this study, we aim to determine whether impulsivity is related to a higher seasonal variation in suicide attempts. Our goal is to measure the impact of seasonality (attempts by month of the year) in suicide attempts by subjects with higher impulsivity levels, as measured by Barratt Impulsiveness Scale, when compared to subjects with lower impulsivity levels. To our knowledge, this is the first study that assesses the Barratt Impulsiveness Scale a possible marker of seasonality in suicide attempts, which could help identify patients that have greater risk during certain months of the year.

Measurement Invariance of the Barratt Impulsiveness Scale across Black and White Adults with Cocaine Use Disorder
Addictive behaviors, 2020Co-Authors: Angela M. Haeny, Brian D. Kiluk, Charla Nich, Donna M. Lapaglia, Kathleen M. CarrollAbstract:Abstract This study tests for measurement invariance of impulsivity assessed by the Barratt Impulsiveness Scale (BIS) across Black and White adults with cocaine use disorder and examines the association of BIS impulsivity with treatment retention and outcomes. Data from four clinical trials were combined providing a total sample of 302 participants with cocaine abuse/dependence (42% Black, 58% White, 44% female, agemean = 40.22, SD = 9.26). We used multi-group confirmatory factor analyses to test for measurement invariance across race and examined bivariate correlations between BIS impulsivity and treatment retention and outcomes by race. Factor analyses indicated a 22-item, two-factor (motor Impulsiveness and nonplanning Impulsiveness) brief BIS fit the data best (RMSEA=.073 [90% CI: .065-.080]; CFI=.904; TLI=.893; SRMR=.073) and was configural, metric, and scalar invariant across race. Higher motor Impulsiveness was associated with higher percentage cocaine negative urines in the overall sample (r = -.15, p=.01), but this association only remained in the Black subsample when examined across race (r = .28, p

Higher motor Impulsiveness was associated with higher percentage cocaine negative urines in the overall sample (r = -0.15, p = .01), but this association only remained in the Black subsample when examined across race (r = 0.28, p < .001). Higher motor Impulsiveness was also associated with increased days abstinent from cocaine in the Black subsample only (r = 0.28, p < .001). Nonplanning Impulsiveness was associated with lower percentage of treatment days abstinent from cocaine in the White subsample only (r = -0.16, p = .045). These findings 1) provide evidence for a 21-item, two-factor brief BIS that is invariant across Black and White adults with cocaine use disorder, and 2) suggest that BIS impulsivity may be associated with poorer cocaine treatment outcomes among White but not Black adults.
